Abstract
A cause of work loss in a factory that produces high-mix low-volume products is extracted. The analysis system includes: a calculation unit; a storage unit; and an input and output unit. The storage unit stores record information related to operation time of an activity for producing a product, and threshold information for determining whether the activity of producing the product is abnormal based on the operation time. The calculation unit is configured to determine the operation time and non-operation time for each case extracted from the record information, determine abnormality for each case based on the operation time for each case and the threshold information, and output information of comparing the operation time of a case determined to be abnormal with the operation time of a case not determined to be abnormal to the input and output unit.
